Network Assessment process: step 5VoIP Line test - the VoIP call is simulated toassess jitter and packet loss for theconnection. Collected metrics are used ingenerating a Mean Opinion Score (MOS)value.The MOS provides a numerical indication ofthe perceived quality from the users'perspective of received media aftercompression and/or transmission.The MOS is expressed as a single number inthe range 1 to 5, where 1 is lowest perceivedaudio quality, and 5 is the highest perceivedaudio quality.a. What range should I be in?i. Jitter - 2msii. Packet loss - 0.50%iii. MOS - 3.5SIP ALG Firewall must be NO.Service will not work with SIP ALG ON14
Network Assessment process: step 6Speed Test - tests the speed and quality ofthe user’s Internet connection.Bandwidth is the maximum rate at whichyour network can transfer data.It is one of the key factors in the overallnetwork assessment test since it determineshow many concurrent phone calls aconnection can support.15
Network Assessment process: step 7The upload capacity is the upload capabilityof the connection. It is the maximumamount of data the connection can send(upload), measured in megabits per second(Mbps). This number is typically lower thanyour download speed and reflects the actualupload bandwidth available to the localcomputer.The download capacity is the downloadcapability of the connection. It is themaximum amount of data the connectioncan receive (download), measured inmegabits per second (Mbps). This number istypically higher than your upload speed andreflects the actual download bandwidthavailable to the local computer16
Network Assessment process: step 8The DHCP Service Availability test checks ifa DHCP Server is available on the network,and if determines which DHCP Serveroptions are presented (e.g. DNS IP’s, andNTP Servers. )17
Network Assessment process: step 9The VOIP Download line graphThe red graph indicates the delayreported over the duration of the test.The blue graph is the transfer speed inkbps over the duration of the test.18
Network Assessment process: step 10Round Trip Time Consistency: Round triptime for the packets used in each test casemeasured between the client and NetworkAssessment Appliance.19
Network Assessment process: step 11The results for the tests are all GreenBased upon these results yourenvironment will work with AT&TCollaborate for a quality voice call.20

Suggested Areas of ImprovementsRed, Yellow and White circles on the summary page
Suggested improvement areasRed, yellow or white circles on summary pageThese improvements allow Collaborate to provide an excellent service.The Network Assessment Tool is not recommended to be used with AVPN networks.1.28Firewall: If one or more of the 29 ports tests on the Firewall fails (Red, White or Yellow circles on thesummary page): Please engage your Firewall vendor to open the layer 4 ports that failed. Firewalls can exist asappliances anywhere within the LAN environment. A Firewall can also sometimes exist outsidethe LAN, in the case of cloud-based Firewall services. A Firewall can also exist as a software service on any networking device in the LAN. The layer-3routing devices can have active Firewalls or Access Control Lists (ACL) that prevent this VOIPtraffic from working with Collaborate. Examples of routing devices that contain softwareFirewalls are: MIS CE router, MIS virtual CE router, AT&T Business Internet Service ResidentialGateway (RG), SOHO (Small Office Home Office) Wi-Fi router, or load balancer, etc. The Personal Computer (PC) could have its own Firewall. The software/hardware providerwould need to make changes to allow the necessary ports to work with Collaborate. Note thata personal comput
